Scientists propose three-step method to reverse significant reforestation side effect
Reforestation efforts using a monoculture of a fast-growing tree species, while effective, significantly impact the soil water content of humid, tropical regions and threatens global freshwater supplies. Scientists have now found that the transpiration rate and transpiration-related trait values are up to 10 times greater in the fast-growing species than nearby, dominant slow-growing species. The team has proposed a three-step method for ensuring reforestation efforts in tropical regions don't harm the surrounding soil water content. (2021-02-10)

Green Deal: Good for a climate-neutral Europe - bad for the planet
Europe is to become the first climate-neutral continent- this goal of the 'Green Deal' was announced by the EU in late 2019. Carbon emissions shall be reduced, while forestation, agriculture, environmentally friendly transport, and renewable energies shall be pushed. In Nature, scientists of Karlsruhe Institute of Technology (KIT) show that this ''Green Deal'' might be a bad deal for the planet, as the EU will outsource environmental damage by high imports of agricultural products. (DOI: 10.1038/d41586-020-02991-1) (2020-11-12)

RUDN University soil scientist: Deforestation affects the bacterial composition of the soil
A soil scientist from RUDN University studied the effect of forest conversion on the properties of the soil: its acidity, carbon and nitrogen resources, bacterial composition, and the activity of microorganisms. The study can help improve the methods of soil cultivation after deforestation, namely, select the best fertilizers, prevent erosion, slow down nutrient depletion, and balance the composition of the bacterial community. (2020-11-09)

Soil carbon changes in transition areas suggest conservation for Amazon, scientists say
Conservation efforts on the edges of the Amazon forest, especially in light of recent deforestation by human disturbance, could help the region weather the storm of climate change, researchers say.

Study reveals impact of centuries of human activity in American tropics
The devastating effects of human activity on wildlife in the American tropics over the last 500 years are revealed in a new study published today. More than half of the species in local 'assemblages' - sets of co-existing species - of medium and large mammals living in the Neotropics of Meso and South America have died out since the region was first colonised by Europeans in the 1500s. (2020-09-15)

Reforestation can only partially restore tropical soils
Tropical forest soils play a crucial role in providing vital ecosystem functions. They provide nutrients for plants, store carbon and regulate greenhouse gases, as well as storing and filtering water, and protection against erosion. Scientists at the University of G├Âttingen and Minnesota investigated how the properties and ecosystem functions of tropical soils change when forests are cut down, and whether reforestation can reverse such soil degradation. The results are published in Nature Reviews Earth & Environment. (2020-09-15)

Older and richer: Old grasslands show high biodiversity and conservation value
Researchers from the University of Tsukuba and Kobe University have found that the long-term, sustained existence of grasslands can increase plant diversity, and can act as an indicator for grasslands of high conservation importance. Old grasslands showed a higher plant diversity than forests and new grasslands, and acted as refuges for native and endangered grassland-dependent plant species. The plant community of old grasslands was shown to be unique, indicating that they are of high conservation priority. (2020-09-10)

Degradation outpaces deforestation in Brazilian Amazon
The area of the Brazilian Amazon affected by forest degradation--where forest biomass is lost but not completely converted to another use--is greater than the area affected by deforestation, according to a long-term study by Eraldo Aparecido Trondoli Matricardi and colleagues. (2020-09-10)

Study shows efforts in mangrove conservation and restoration paying off
In recent times, mangrove deforestation has raised alarms about increased carbon emissions into the atmosphere. Research led by the Singapore-ETH Centre shows that the net amount of carbon released from deforestation between 1996 and 2016 globally is only 1.8% - or less than 0.1% of global CO2 emissions. The new approach of quantifying net losses of mangrove carbon stocks is the first to take into account mangrove expansion through conservation, restoration, and natural establishment. (2020-08-28)

Growing demand for zero-deforestation cacao might not help Colombian forests
Cacao in Colombia is not a major driver of deforestation - yet. But increased demand could imperil forests in the future. New research shows cacao stakeholders have to overcome barriers to reach markets that value zero-deforestation, complicating one of Colombia's post-conflict strategies. (2020-08-27)
